Never seen this before TMI sorry

So my husband and I have been trying for baby #3. About 4 days ago I went to use the restroom and notice this, I have never seen this or had this happen to me before so I'm not sure what it is.. I researched online( I know not a good place to go for answers) and half of what I got was I could be pregnant and the other half of what I read was I'm fertile. Again I've never seen this before so anyone else experience this and happen to be pregnant? Also this been happening every day for about 4 days now
